thats not what im asking. Lets completely forget that I'm asking about the NICS and ECCS differences. I'm asking how can I hook up my bare ECCS RB20 Silvertop intake manifold to my RB20 ECCS Silvertop head. I'm doing more research and it looks like I'm needing an IACV valve, the underside coolant passages, I need to know about connectors and which ones I need.

Maybe I should rephrase my question as I am now seeing how confusing it is. I currently have the ECCS head on the NICS Block but this shouldn't matter. SPECIFICALLY WHAT I NEED is how to hook up the (ECCS) intake manifold to the (ECCS) head I am also using an EBAY front facing plenum.

I need to know what is required. Like, certain electronic connectors, physical connectors, and any vacuum lines. I managed to get a BARE RB20 ECCS head for free for my NICS engine so I thought I would just swap it and it also allowed me to replace the head studs with ARP head studs.
